Trakpower 4900

[frogger]

I got my Trakpower battery today and I want to balance/charge it using my FMA Cellpro 4s 4Amp charger. I am totally new to LiPo so need to know how to connect it so it balance charges.

I have the FMA Cellpro connector with 5 wires (red wire, 3 white node wires and black wire). I have spoken with FMA and they said that I need to connect:
Black to Black
Red to Red
White (Node 1) closest to Black to the middle pole (to read 3.7V).

I assume the little hole in the middle of the Trakpower battery between the positive and negative pole is the middle pole? I have tested it and it reads 3.7V.

If so, where do I get the connector (and what type is it) to connect the white wire to the middle pole. It seems quite a bit thinner than a corally.
